I think I have found the final bit of proof to the argument that James Jamerson used LaBella Flatwound Strings; In a Guitar Player interview from 1979, JAMERSON, states about his 62 Fender P Bass (The Funk Machine) That pretty much wraps it up for me folks. I am not too concerned about what some producer says ect. James Jamerson said he took the stock strings off the bass and put LaBellas on it when he got it. That must be where the "rumor" came from. Jamerson says in the same article that in the last years of his life, bass players were contacting him and asking him what strings he used ect. James replied that the sound was not in the strings, it was in his heart. I could not agree any more. I have LaBellas on my P Bass and I play the same lines James played and I don't sound anything like the man. But the LaBellas do sound very good on my P Bass and maybe that is as close to sounding like James as I will ever get.
